Weatherman Walking

On a mission to dig out some of his greatest adventures from the past, Derek revisits three memorable walks from mid-Wales. On his first wander, he is joined by opera singer Beverley Humphreys as they walk in the footsteps of one of history's most impressive sopranos atthe Craig-Y-Nos estate. He learns of the epic barefoot 26-mile journey of a devoted teenage girl in Abergynolwyn. Finally, Derek takes the plunge at the bog snorkelling world championships in Llanwrtyd Wells.
